Hello there,
I tried to generate report with +C"OUTPUT COMPUTER" directive in Alpha
OSF1 Tru64 5.1A.
And I got the following run-time error:
$ ./analog +C"OUTPUT COMPUTER"
x VE analog 6.0
x HN [my organisation]
x PS 2005 09 26 10 44
x FR 1999 12 31 10 11

x SR 46
x PR 44
x FL 2
x RR 2
x NF 4
x NH 2
x BT 49918
m RP Floating exception(coredump)
When I debugged the core file using "ladebug",
$ ladebug ./analog core

The problem is due to div. by Zero, since unit variable (double type)
in barchart() function of output2.c has a zero.
Then I changed the following in output2.c,
$ diff -r output2.c.new output2.c
715,716c716
< if(unit){
< x /= unit;}
---
> x /= unit;
It seems to work fine. The report if fully generated.
Is this a possible bug ??
